Some observations...

TreeColumn 

Aligment is not consistent. When I specify IconAlignmentRight the Icon is drawn correctly, but the tree structure remains left aligned.

Also tooltip does not show in the area reserved for the treestructure.

 

AddCombo / ConstraintEdit.

Add some constraints and a Combobox to a (header) item. Then set the Caption of the item to s'thing NOT in the constraint list. e.g. "[Click to edit]".

The user cannot "clear" that caption: whatever he selects from the dropdown remains invisible.  Intended behaviour?

 

I' use an InsideButton to allow removal of rows.  I then use RemoveAt Row.Record.Item to remove that row.  The first time a user clicks the button all is ok. but when he presses another Remove button the form hangs. After I added a  DoEvents after RemoveAt the hangs no longer occur, but it's a bug.  Also I don't like the selection/focus is set to the first (visible?) row when I remove a row in the middle of the report. It should be on the record below the item removed.

 

Where can I set the style/appearance of the scrollbars and the inside dropdown, or are they always controlled by the OS?

I've bought SuitePro for styling reasons. I can set appearance for many other suitecontrols, but scrollbars seem to be OS styled. UGLY.
